Energy-saving aluminum smelting equipment

The utility model relates to energy-saving aluminum smelting equipment which comprises a smelting furnace, ultrasonic frequency smelting equipment and a heat preservation furnace. The ultrasonic frequency smelting equipment provides heat for the smelting furnace, and the heat preservation furnace is used for preserving waste heat of the smelting furnace. The ultrasonic frequency smelting equipment comprises three layers including the master control layer, the filtering IGBT driving layer and the output capacitance layer. The output end of the output capacitance layer is connected with the smelting furnace. The smelting furnace comprises a furnace body and a furnace lid arranged at the upper portion of the furnace body. The furnace body is of a hollow structure. A water inlet pipe and a water outlet pipe are arranged at one end of the furnace body. The water outlet pipe is connected with the heat preservation furnace. A circular groove is formed inside the furnace lid. An induction coil is arranged on the periphery of the circular groove. The induction coil is connected with the output capacitance layer. A crucible is placed inside the circular groove. A cement partition wall is installed at the lower portion of the crucible. A jacking platform is connected to the bottom of the cement partition wall. A lifting rod is connected with the lower portion of the jacking platform. One end of the lifting rod is connected with the jacking platform, and the other end of the lifting rod is connected with a motor. The motor is connected with a supporting frame. The two ends of the supporting frame are both connected with the bottom inside a furnace body. In conclusion, the energy-saving aluminum smelting equipment has the advantages of saving energy, and being convenient, rapid and efficient.
